⚡ Charging Guide for Mercedes EVs with 22 kW AC Onboard Chargers
Several Mercedes-Benz electric vehicles — including the EQA, EQB, EQE, and EQS — offer a 22 kW AC onboard charger as an optional upgrade. If your vehicle includes this feature, you can charge at one of the fastest AC speeds available, whether at home or on public infrastructure.
When connected to a 32A three-phase supply, your Mercedes can add up to ~77 miles of range per hour, making daily top-ups and full recharges far quicker and more convenient.
🏡 Maximise AC Charging at Home
To take advantage of the full 22 kW charging speed, you’ll need a three-phase 32A wall box and a compatible Type 2 charging cable. This setup is ideal for drivers with larger battery packs, high mileage, or limited home charging windows.
